| | THALLIUM(I) ACETATE Usage And Synthesis |
| Chemical Properties | White to off-white fine crystalline powder | | Uses | Acetic Acid Thallium(1+) Salt, is a Thalum salt, considere to be a hazardous material.It can be used as in Chemical Synthesis, Micro/NanoElectronics, and Materials Science. | | Uses | Rodenticide, insecticide; fireworks dye; in optical glass; depilatory. | | Uses | Thallium acetate is used in high
specific gravity solutions to separate ore constituents by flotation.
It was formerly used as a depilating agent by dermatologists
via oral administration in cases of ringwormof the scalp,
causinga number ofdeathsand poisonings.Thallium(I) acetate
(0.1M) is used to enhance phosphorescence emission on laserinduced
room-temperature phosphorimetry. | | Production Methods | Thallium acetate is prepared from thallium(I) hydroxide or
carbonate and acetic acid, which are then evaporated and
recrystallized from alcohol. | | Definition | ChEBI: An acetate salt comprising equal numbers of acetate and thallium ions. | | General Description | White odorless crystalline solid. Density 3.68 g / cm3. A dangerous poison. | | Air & Water Reactions | Deliquescent. Soluble in water. | | Reactivity Profile | THALLIUM(I) ACETATE gives aqueous solutions that are basic (neutralize acids). These neutralizations generate only a little heat. Neither a strong reducing agent nor oxidizing agent, but can serve as both. | | Health Hazard | Thallium is one of the more toxic elements both as an acute and a chronic poison. Effects of exposure are cumulative and onset of symptoms may be delayed 12 to 24 hours. May be fatal if inhaled, ingested or absorbed through the skin. Irritating to skin and eyes. Readily absorbed through the skin and digestive tract. Ingestion of soluble thallium compounds has caused many deaths. Ingestion of sublethal quantities may cause nausea, vomiting, diarhea, abdominal pain, and bleeding from the gut accompanied or followed by drooping eyelids, crossed eyes, weakness, numbness, tingling of arms and legs, trembling, tightness and pain in the chest. Loss of hair may occur in two to three weeks. Severe intoxication may cause prostration, rapid hearbeat, convulsions, and psychosis. Some effects may be permanent. | | Safety Profile | Human poison by ingestion. Experimental poison by ingestion, intravenous, intraperitoneal, and subcutaneous routes. An experimental teratogen. Mutation data reported. When heated to decomposition it emits toxic fumes of T1. See also THALLIUM COMPOUNDS. |
